description Process making it possible to lower the degree of recrystallisation of aluminium and of its alloys and to reduce the grain size to a minimum. It consists in adding less than 2500 ppm of scandium to the metal at the time of its production. This process applies especially to the production of aluminium-based metal sheets intended to be subjected to a treatment at a relatively high temperature such as, for example, that accompanying rolling, enamelling, welding and soldering operations, this being without this treatment being capable of resulting in an excessively high recrystallisation which would be detrimental to the mechanical properties of the said sheets. L'invention est relative à un procédé, permettant de diminuer le taux de recristallisation de l'aluminium et de ses alliages et de minimiser la taille des grains.Elle consiste à ajouter moins de 2500 ppm de scandium au métal au moment de son élaboration.Ce procédé s'applique notamment à l'obtention de tôles à base d'aluminium destinées à être soumises à un traitement à température relativement élevée, comme par exemple, celui qui accompagne les opérations de laminage, d'émaillage, de brasage, de soudage et ce, sans que ce traitement puisse entraîner une recristallisation trop importante qui nuirait aux propriétés mécaniques desdites tôles.
